Claims that Tor and Onion Service can secure API traffic by keeping it entirely inside the Tor network, hiding metadata and removing dependence on DNS or CAs; network runs ~6–7k relays with ~300 Gbps capacity and ~150 Gbps typical usage and 2–8M daily users. Onion addresses are 56-character self-authenticating address (hash of the service public key) so impersonation is infeasible, you need no HTTPS needed or SSL certs, no port forwarding or firewall changes, demo exposes a Flask API and SSH over Tor and works though latency is higher due to three-hop routing.
